michelle obama is most important. the two most popular figures in the democratic party are michelle obama and bill clinton. it's no cept the surprise one id tonight and one is tomorrow night. i think it's important to communicate. it's been an advantage the president has and it's had over governor romney throughout this campaign, even inspite of the abc poll, until i see further evidence will consider a bit of anouan outlier and the presidens better liked than governor romney. and romney's own people, they will never be competitive at that level with president obama. if they're going to win this race, they have to win it onç other issues,ç the economy and his perceived confidence in business. >> woodruff: what about the most of the mayor of san antonio, not a national name, chosen to give the keynote address. >> there was a state governor from illinois more strings than castro just eight years ago. i think it highlights not the importance over sang tony or even the great state of texas of latinos and hispanic vote
